Trying to build Tango as dynamic library on linux

[jpf]

Hi,
are you still working on that? I tried to use druntime as a dynamic library on
Linux, and I had exactly the same problem. (version node not found for symbol
_d_throw at 4)
Googling showed that this problem has been discussed before:
http://digitalmars.com/d/archives/digitalmars/D/libphobos_as_.so_54793.html

So because of the extern(Windows) / _stdcall calling convention, dmd emits the @4
( http://en.wikipedia.org/wiki/Name_mangling#C_name_decoration_in_Microsoft_Windows
)
If I understand this
http://people.redhat.com/drepper/symbol-versioning
correctly, ELF uses symbol names like _d_throw at 4 as name at version. As there is no
entry for version 4, linking fails. I guess mac is not affected, because Mach-O
accepts _d_throw at 4 as a symbol name.

It seems like nothing has changed since then.

_d_throw is still extern(Windows) / _stdcall and i guess dmd would still emit calls
to _d_throw at 4 if _d_throw was changed to extern(C).

Btw: Someone seems to have found a basic workaround for the name mangling problem:

But i guess, this should really be fixed in the compiler and druntime.
